FAQ About Grigori Perelman

The Poincaré Conjecture is a fundamental question in the field of topology that proposes a characterization of the three-dimensional sphere among all three-dimensional manifolds. It essentially asserts that a simply connected, closed 3-manifold is homeomorphic to a 3-sphere. Grigori Perelman provided a complete proof of this conjecture in the early 2000s, which was verified and acclaimed by the mathematical community as valid, solving one of the most profound mathematical enigmas of the 20th century.
